Summary: Achieving zero-waste of municipal solid waste (MSW) is a vision of policymakers and scholars. This study summarized a strategy formulation path towards zero-waste of MSW and built a dynamic model to simulate the zero-waste situation of Shanghai' MSW. Following the goals of zero landfill, more recycling, and less generation, three stages towards zero-waste of MSW were identified.

Summary: With the increase in people's living standards, textile waste and furniture waste have become significant environmental challenges. This study proposes a solution that combines sustainable design with composite material manufacturing to address these challenges. The study developed a waste textile-starch composite material using microwave expansion technology, which is biodegradable, environmentally friendly, and customizable. The material was then applied to sustainable furniture design, resulting in a set of design works with sustainable characteristics. This reform scheme shows promise for sustainable development and can effectively address the issues of textile waste pollution and furniture resources.

Summary: This study proposes a novel process design for converting lignocellulosic biomass into ethanol with zero waste generation. It demonstrates the feasibility and profitability of producing ethanol while converting waste streams into high value-added by-products. The results show that co-production of by-products can significantly decrease the minimum viable sales price of ethanol and that the price of lignin has a significant impact on the profitability. Additionally, the study suggests that the proposed process can avoid water pollution through water recycling, but there is a trade-off between reduced water pollution and increased CO2 emissions when fossil fuel is used as the energy source.

Summary: A study was conducted to design and analyze an integrated biodiesel biorefinery using a circular economy approach to achieve better economics and a zero-waste scenario. Different scenarios were evaluated based on profitability, sensitivity, and environmental analysis, with one scenario showing the highest profitability and another showing the least. Improvements were implemented to reduce waste production and enhance sustainability.

Summary: This study applies green technology to extract compounds from wastewater-grown microalgae biomass, aiming to obtain microbiologically safe products in a sustainable biorefinery process with zero waste. The impact of subcritical water extraction conditions on the chemical and microbiological profiles of the obtained extracts and residues is investigated. The extracts and residues of Tetradesmus obliquus are found to contain valuable compounds such as hydrocarbons, phenols, esters, and ketones. Increasing the temperature and supplementing with CO2 enhance the polyphenolic content and antioxidant activity. The liquid extracts and residues are determined to be safe sources of bioactive components for different industries. The lower content of heavy metals in the residues suggests their potential use as animal feed or soil conditioner.

Summary: There is a current wave of new digital solutions, such as intelligent systems and AI-driven optimization tools, that are based on quality-related information within the supply chain ecosystem to ensure quality in smart factories. These solutions aim to empower zero-waste value chain strategies by providing meaningful, reliable, and trustworthy data. To achieve this, the paper presents Product, Process, and Data quality services as well as a Trusted Framework (TF) for secure and effective sharing of quality-related information.

Summary: Zero waste plays a crucial role in the circular economy model by manufacturing recyclable products instead of fast-moving consumer goods, reducing waste, and implementing recycling/reuse technologies to ensure resource efficiency. This study aims to identify the barriers to zero waste management in Turkey, with a focus on the lack of clarity in circular economy goals and tactics, as well as the absence of financial and economic support. Through fuzzy DEMATEL methodology, it is found that these barriers are interdependent and uncertainty in goals and tactics, along with financial constraints, are significant barriers affecting zero waste management success in Turkey.

Summary: The overgeneration of non-biodegradable waste in Indonesia has led to the need for empty lands for landfilling, which goes against the principles of sustainable cities. To tackle this problem, Indonesia is gradually adopting digitalization in waste recycling to add economic value to recycled waste and promote waste avoidance through economic incentives. The study shows that the digital transformation of the waste industry not only promotes resource recovery and a circular economy but also enables local communities to engage in online transactions of recycled goods using mobile-based applications.
